Be it known that I, Gnome Human r Bm amwrnvfacitizen of the UnitedStates,

51 -in'to-the shuttle. r v "The object of my invention is to producetransverse section on the line 11-41 of Fig.

residin in the city, county, and State of New" ork,"-have inventedcertain new and euseful Improvements in Bobbins, of which the followingis a specification.

invention relates to bobbins of the type whichf'are"speciallyedapted foruse with leoms wherebobbins are automatically fed a bobbin in whichtherings on the lower paitof the 'bobb1n, which coact with theinte'ri'orof'th'e shuttle, shall be so arranged as to retain their spacerelation and fun thenthat the tube on the interior of the base of thebobbin, which coacts wit the shank ,oi clutchof the spindle whirl, shallbe so corresponding in height with the acting surfacesiof the clutch andmaintain a fixed pbsition relative to the body of thebobbin, and"thus'be.prevented from turning within the bobbin'or dropping out of thebobbin,

owing to the shrinkage of the material of which-the bobbin is made, etc,

ffA- f1irther object of my invention is to provide a base for a bobbinwhich may read- -il'y" be secured to old shankswhich have split at? thebase, and thus al low the rings to dro'pofi. r o v 'The accompanyingdrawings will serve illustratelmy' invention, in which Q Eigure 1 is aside elevation.

portion consists of a tubular member 16,

basemember 17, arm members 18, provided with horizontal grooves 19, andring members 20, which may be of well known construction and secured inposition in the usual manner. The tubular member 16 is adapted tor-fitwithin the cavity l5 of the head 11; the base member 17 to be locatedunder the bottom of the head 11; the arm members 18 in the grooves 13,and'the ring members 20in thegrooves 12 of the head 11, and in thegrooves 19- ofthe arm members 18v It will be observed that the grooves19 of the arm members 18 are in alinement' with the grooves 12, and asthe arm members 18 have the grooves 19 deli nitely .spaced, the ringmembers 20 will be held in a defined position as regards each other, andirrespectiveof shrinking or splittingolt' the head 11 (with theconsequent displacement of the grooves 12), and further, that as the armmembers 18 are situated in grooves 13-of the head 11, there can be norotation of the tubular member 16 within the cavity 15 of the head 11,which rotation is apt to occur by the frictional resistance between thetubular member and the driven whirl, shank or clutch, when, a tubularmem. her is inserted into the base of a bobbin and ot secured therein,except by the pressure due to the resilient action of the material ofwhich the bobbin is made.

21represents a spindle whirl, provided wit-ha shank E22 and clutch 23:It will be observed thatthe clutch 23 coacts with the interior of thetubular member 16. Manifestl'y the shape of the tubular member may beany thatisrequired to dooperate with any special design of. clutch, oras is usual, it may bexcone-shaped so as to cooperate with the ,ordinarycone-shaped spindle shank.

tubular member 16 is pressed into the wood at 27. Any other means ofsecuring the 1 base member to the head 11 may be adopted.

In all of the figures, I have shown the interior tubular member and theexterior memhere as formed of a single pieceof metal.

Manifestly, for convenience of manufacture or otherwise, the tubularmember, the base "member, the arm members or theexterior shell m mber,can allbe formed of separate pieces or material secured by. rivets orotherwise .without in any'wis'e 'de arting from the intent of myinvention.

t will be observed that in the construction shown in Fig. 6, the headportion 11 contains less mater al than in the construction shown in" 1and 2, the difference in diametenof the head 11 being com ensated. forby the base (Fig. 7).
